Central America: found only in the humid montane forests of Costa Rica and western Panama.
A restricted-range species. Common in parts of its range.


This is a monotypic species[1].
It's sometimes considered conspecific with Yellow-green Brushfinch and both have in the past been placed in genus Pselliophorus.


Humid mountain forests, second growth, bamboo clumps, scrubby pasture and bushy clearings. Occurs at 1200 m to the treeline mostly above 1500 m.


An active and noisy bird.


The female builds the cup shaped nest, hidden in coarse grasses, bamboo or thick foliage. The 2 white or pale blue eggs have brown blotches and are incubated by the female for 12-14 days.


They feed on, or near the ground, on insects, spiders, berries and nectar from tubular flowers. Will take seeds when available.
